The term "trochanter major" refers to a bony prominence found on the femur (thigh bone). It is also known as the greater trochanter. This anatomical structure serves as an important attachment site for muscles and tendons in the hip region. Synonyms for trochanter major include great trochanter, large trochanter, and greater femoral trochanter. These terms are often used interchangeably in medical literature and discussions. Their primary function remains constant, denoting the prominent protrusion on the femur that facilitates rotation and movement in the hip joint, playing a crucial role in lower limb biomechanics and locomotion.
